IncludeOtherPages

The (:include:) directive makes it possible to insert (or "transclude") the contents of other pages into the current wiki page. All of the include directives below perform a straight text inclusion. In particular, any page links in the included text are assumed to link to pages in the current group if not otherwise qualified.

includes a page according to the parameters supplied. Parameters are optional.

Parameters

The directive can have multiple Name parameters with or without anchors, and multiple template variable parameters.

Named pages

(:include PageName:)

(:include Group.PageName:)

(:include Page1 Page2 Group1.Page3 Group2.Page4:)

Includes the entire text of another page into the current page. Multiple pages may be specified, but only the first available is included.

You can use the above feature to display an error message if an include fails. Create a page, eg. Site.IncludeFailed containing the error message. You can use any page name. Then, in your include markup, append this page at the end of the page list:

Note: text on the same line as a closing anchor but preceding the closing anchor will NOT be included in the text. Example Below:

[[#start]]some text on the first line

some text on the last line [[#end]]

The above, when included via (:include PageName#start:) will have the text on the first line but not the text on the last line.

(:include Page1 Page2 #from#to:)

Include from the first available of Page1, Page2 between the [[#from]] and [[#to]]

Note: put whitespace between "Page2" and "#from#to". The same anchors "#from#to" should be in both pages. If proper anchors are missing in the first available of Page1, Page2 the whole contents of the page is included.

Include the first from the first available of Page1 (between the [[#from1]] and [[#to1]]) or Page2 (between the [[#from2]] and [[#to2]] )

Note: Previous versions of PmWiki allowed whitespace between #from and #to anchors even though it was not designed to. Newer versions do not allow whitespace anymore. To re-enable this "exploited misbehavior" put this into your config.php or farmconfig.php

Lines=

(:include PageName lines=10:)

(:include PageName lines=5..10:)

(:include PageName lines=5..:)

Include the first 10 lines, lines 5-10, or lines 5 and up from PageName. A "line" in this context refers to a line of source. Thus a line may be a paragraph that wraps over several lines on the screen, or a completely blank line.

(:include Page1 Page2 Page3 lines=1..5:)

Include the first five lines from the first available of Page1, Page2, or Page3. (To include lines from a list of pages, use a separate include for each.)

Self=

(:include PageName self=0:)

The parameter self can be 0 or 1. It tells the include directive if it is allowed to include the current page. This is useful if PageName is a variable like {$Name} and you want to prevent the directive from including the current page.

Includes definition list values from an (optional) page as page text variables. These are defined using a definition list (:item:description), simple colon delimiter (item:description), or special markup ((:item:description:)).

Basepage=

(:include PageName basepage=BasePageName:)

Include PageName, but treat all relative links and page variables on PageName` as relative to BasePageName.

If basepage= is provided all relative links and page variables are interpreted relative to basepage.
So, if one creates TemplateName as

Name: {$:Name}
Address: {$:Address}

then the directive

(:include TemplateName basepage=PageName:)

will retrieve the contents of TemplateName, treating any page variables and links as being relative to PageName.
In particular, the values for {$:Name} and {$:Address} will be taken from PageName, but things like {$Title} and {$LastModifiedBy} would also work here.

Basepage usage

The primary purpose of basepage is to allow the include of pages in a way that mimics the 2.1.x behavior where page variables
and links are interpreted relative to the currently displayed page.
This is done with:

(:include SomeOtherPage basepage='' :)

-or-

(:include SomeOtherPage basepage={*$FullName} :)

It also allows GroupHeader and GroupFooter to have their page variables and links be relative to the currently displayed page
(instead of GroupHeader and GroupFooter):

Otherwise, using IncludeOtherPages inside of a GroupHeader would display 'GroupHeader' and not the name of the currently displayed page.

The basepage= parameter is general enough that it can also be used as a templating engine, so that
we can grab a template page containing variables that are then filled in with values from another page:

(:include TemplatePage basepage=DataPage :)

And, of course, a single TemplatePage can actually contain multiple templates delimited by anchors, so that we end up with a syntax eerily similar '^[1]Okay, maybe it's not so eerie, given that the pagelist template code actually uses the same function as (:include:) to grab its templates. But it's still a useful parallel. ^' to pagelist-templates:

(:include TemplatePage#abc basepage=DataPage :)

So then TemplatePage can use a syntax like:

[[#abc]]
...template stuff here...
[[#abcend]]

and it's possible to display TemplatePage as a template without it being interpreted... same as we do for Site.PageListTemplates.

[1]Okay, maybe it's not so eerie, given that the pagelist template code actually uses the same function as (:include:) to grab its templates. But it's still a useful parallel.

Specifying variables as parameters

You can also specify variable values inline with the include statement, and refer to the variables in the template using the {$$variable1} format:

(:include TemplatePage variable1="value" variable2="value2":)

This assumes that a site has $EnableRelativePageVars enabled, which is recommended in PmWiki 2.2.0 -- but was disabled by default in version 2.2.8 and earlier.

For example, on my included page ("template") I might have this:

[[#ivars]]
Hi, {$$Name}, how are you today?
[[#ivarsend]]

Hi, {$$Name}, how are you today?

Then, including that section above (that section is available via the section {$FullName}#ivars)) you get this type of behavior:

PmWiki is a wiki-based system for collaborative creation and maintenance of websites.

PmWiki pages look and act like normal web pages, except they have an "Edit" link that makes it easy to modify existing pages and add new pages into the website, using basic editing rules. You do not need to know or use any HTML or CSS. Page editing can be left open to the public or restricted to small groups of authors.

Have a very nice day!

Parameter References

Any parameters supplied to an include statement (whether they are keywords or not) are accessible inside the included page as a special {$$...} variable of the same name. This feature can be used to provide extra information to use when displaying the included page.

Notes

You can also say (:include My/Page#myanchor lines=4:) which starts from, and includes, the line with the anchor [[#myanchor]] for four lines.

By default, PmWiki places a limit of 50 include directives for any given page, to prevent runaway infinite loops and other situations that might eat up server resources. (Two of these are GroupHeader and GroupFooter.) The limit can be modified by the wiki administrator via the $MaxIncludes variable.

Is there any way to include from a group of pages without specifying by exact name, e.g. between Anchor X and Y from all pages named IFClass-* ?

There appears to be a viewing issue when the included page contains the (:title:) directive.

In a default installation, the last title in the page overrides previous ones so you can place your (:title :) directive at the bottom of the page, after any includes. See also $EnablePageTitlePriority.
